Purple Biotech (NASDAQ/TASE: PPBT) has announced the development of IM1305, its second CAPTN-3 tri-specific antibody targeting TROP2. The novel antibody combines a masked anti-CD3 arm, an anti-NKG2A arm, and an anti-TROP2 arm to target solid tumors.
Preclinical results show sustained tumor regression in human triple negative breast cancer (TNBC) mouse models, with significant cell death induction across multiple tumor types at low doses. The antibody's unique design includes a cleavable cap that activates specifically in the tumor microenvironment, potentially reducing off-target effects.
TROP2, the target protein, is widely expressed in major solid tumors including breast, lung, gastrointestinal, and ovarian cancers. The company plans to leverage its platform technology to accelerate development and explore partnering opportunities.
Purple Biotech (NASDAQ/TASE: PPBT), a clinical-stage company focused on developing first-in-class therapies for tumor immune evasion and drug resistance, has announced its participation in the upcoming H.C. Wainwright 27th Annual Global Investment Conference.

Purple Biotech announced final data from its Phase 2 study of CM24 in pancreatic cancer patients at AACR 2025. The study showed significant efficacy in biomarker-enriched subgroups, with up to 90% reduction in death risk in specific patient populations.
Key findings include:
- 78% reduction in death risk for patients with specific CEACAM1 ranges
- 61% reduction in death risk for patients with defined CEACAM1 or MPO levels
- 90% reduction in death risk for patients with high tumor CEACAM1 and low PD-L1 CPS
The combination therapy of CM24, nivolumab, and chemotherapy was well-tolerated and showed improvements in all efficacy measures. The study identified CEACAM1 as a potential biomarker, both in serum and tumor tissue. Based on these results, Purple Biotech plans to conduct a biomarker-driven Phase 2b study, potentially expanding into gastric and biliary tract cancer treatments.
